The great stone-curlew (also known as the great thick-knee) is a large wader, frequently seen along the shores of slow moving bodies of water. These birds are typically nocturnal, but can sometimes be seen during the day, moving slowly and deliberately. They can be quite skittish, often not allowing a close approach. In this case I was photographing from a small boat, so that likely helped me get close without spooking the bird.
When photographing this bird, I was able to circle the rock on which it was standing. This gave me typical front-lit lighting (with the sun directly behind me), as well as back-lighting (with the sun behind the subject).
As I was finishing up photographing this bird, I could tell it was quite comfortable with my presence. Soon it stopped pacing and sat down on the rock to rest in the sun.
